| 摘 要： | 基于像素灰度和基于特征的相关匹配跟踪算法跟踪精度不高，只能匹配定位到整像素点。针对该问题，采用相关函数拟合极值法对整像素匹配点进行亚像素定位。设计一种新的实验方法和基于边缘特征的相关匹配跟踪算法。实验结果表明，该算法可以达到0.1级别的亚像素定位精度。

| Abstract: | Correlation matching tracking algorithm based on pixel gray and character is commonly used. The algorithm based on edge feature is a research hotspot because of its advantages for application. However, this kind of algorithm can just locate to integer pixel for its low tracking precision. A method based on the quadratic surface fitting is selected for subpixel matching through analysis and comparison. A new experiment is designed to show that this algorithm gets as high as 0. 1 level of pixel location precision. |
